Ok, here's the scenario.
I have a long list of urls in one column. There are some that match (say 20 point to google.com, 10 point to facebook.com, etc.). What I need to achieve is to display in the next column, next to every single url, count of how many times it is present in the list. So the list will go:
google | 20
google | 20
google | 20
facebook | 10
facebook | 10
etc., etc
